FIELD OF THE INVENTION

This invention relates to the field of adapters for dispensing aerosol.

BACKGROUND

An aerosol spray is a type of dispensing system which creates an aerosol, or mist of fine particles. Typically, this may be accomplished with a pressurized container, such as a can or bottle that contains a substance and a propellant, and a valve such that when the valve is open, the substance is forced out of a small hole and emerges as an aerosol. Aerosol containers, however, come in many shapes and sizes that may prohibit accurate dispensing of aerosol if the location to be sprayed is not easily accessible. When aerosol cannot be easily and accurately sprayed, it may result in waste of material, damage to surrounding objects, and pain or discomfort to an operator required to maintain uncomfortable or extended positions to increase accuracy.

FIGS. 15 and 16 illustrate embodiments of a nozzle cap 5 in accordance with the disclosed concepts. The nozzle cap 5 may be cylindrical in shape and include a top surface 52 and a side wall 50. The nozzle cap 5 may further include an airflow passage ending in a nozzle 53, which may be located on the side wall 50 of the nozzle cap. As discussed above, the nozzle cap 5 may include an actuator 51 which can control the airflow though the nozzle cap 5. As shown in FIGS. 1, 15 and 18, the nozzle cap may include a push actuator 51, wherein the airflow passage is closed when the push actuator is in the resting state. When a user pushes down on the push actuator 51, the airflow passage is opened, allowing the nozzle to disburse the contents of the aerosol container 10. Persons of skill in the art will recognize that any suitable actuator known in the art or to be developed may be used in accordance with the disclosed concepts.

FIG. 17 illustrates a tube 4, which may connect the valve stem 3 to the nozzle cap 5. The tube may be cylindrical in shape, elastic, and may have ends 41 and a side wall 40 defining a cavity 42 therebetween. The tube may be made of polyurethane, or of any other suitable material known in the art. Persons of skill in the art will recognize that the tube 4 may have any size and shape that is suitable for the desired use and the aerosol container upon which it is being used. The tube 4 may be connected to the valve stem 3 and the nozzle cap so that the contents of the aerosol container 10 may flow through the valve stem 3 into the tube 4, into the nozzle cap 5, and out the nozzle 53. The tube 4 may be manufactured in various diameters and lengths to modify the flow rate and increase in extension from the dispensing adapter valve 1 to suit different applications.

As shown in FIG. 18, the dispensing adapter valve 1 may be attached to an aerosol container 10. The support structure 2 may first be clamped onto, or otherwise secured to the aerosol can 10. In embodiments with an adjustable collar 20, once the collar is placed over the aerosol container 10, it can be adjusted to secure the support structure to the aerosol container 10. Once the support structure 2 is secured to the aerosol can 10, the valve stem 3 may be connected to the tube 4 and the nozzle cap 5, and attached to the support structure 2. In embodiments where the valve stem 3 has threading 36, the valve stem may be screwed into place by rotating the handle until the inlet 34 pushes against the pressure valve on the aerosol container 10. This will activate the valve of the aerosol can, and begin to push the contents of the aerosol can into the valve stem. In embodiments such as the where there is an actuator 31, 311 on the valve stem 3, as shown in FIGS. 2, 8, 9 and 18, the activation of the actuator 31, 311 allows the contents of the aerosol can to enter the upper portion of the valve stem 33, pass into the tube 4, and to the nozzle. Similarly, in embodiments where there is not an actuator 31, 311 on the valve stem 3, as shown in FIGS. 1 and 7, the airflow through the cavity in the valve stem remains open and the contents of the aerosol can pass through to the nozzle cap once the inlet 34 in the valve stem 3 depresses the pressure valve of the aerosol container 10. In embodiments where there is an actuator 51 in the nozzle cap 5, as show in FIGS. 1, 15 and 18, the contents of the aerosol container cannot pass through the nozzle 53 until the user activates the actuator 51.
